Typical swarm locations
Collectors regularly attend swarms in the riverside willows and reed-bed margins of the Bure at Acle Bridge, along the drainage dyke vegetation of Halvergate Marshes, in the mature lime and horse chestnut of the older village properties and churchyard, in the hedgerow oaks and bramble of the Beighton and Damgate lanes, and in the chimney stacks and roof spaces of the older brick and flint buildings on The Street and Norwich Road.
